A vessel, such as an insulated container, for liquids having a lower portion sealed with an upper portion, such upper portion having a drinking reservoir for holding liquid which is pumped from the lower portion through a dispensing passage, such as a liquid dispensing tube, by a pump mechanism coup
A vessel, such as an insulated container, for liquids having a lower portion sealed with an upper portion, such upper portion having a drinking reservoir for holding liquid which is pumped from the lower portion through a dispensing passage, such as a liquid dispensing tube, by a pump mechanism coupled with the upper portion. The pump mechanism is ergonomically operable by way of depressing a feature of the pump mechanism, e.g., by a single finger of the same hand holding the vessel. The upper portion, coupled with the pump mechanism, is redisposable on the lower portion, transposable in relation to any other lower portion, and retrofittable in relation to any other interfaceable pre-existing containers. The pump mechanism is optionally provided with a button or soft membrane. The components of the vessel are easily disassembled and reassembled for facilitating cleaning thereof.

1. A pump mechanism comprising: a pump membrane;a one-way pump outlet valve operable to pass a first fluid from the pump membrane to a pump air outlet;a closable flap including: a seal portion operable to seal a liquid exit, anda liquid deflector including a cupped portion extending outside the seal
1. A pump mechanism comprising: a pump membrane;a one-way pump outlet valve operable to pass a first fluid from the pump membrane to a pump air outlet;a closable flap including: a seal portion operable to seal a liquid exit, anda liquid deflector including a cupped portion extending outside the seal portion to redirect a direction of exit of liquid from the liquid exit;a spout rod including a first end coupled to the closable flap;a depressor valve coupled to a second end of the spout rod, the depressor valve positioned inside the pump membrane, wherein actuating the depressor valve displaces the spout rod, opening the closable flap. 2. The pump mechanism of claim 1, wherein compressing the pump membrane to a substantially compressed position actuates the depressor valve. 3. The pump mechanism of claim 1, wherein the closable flap is biased to close upon deactuation of the depressor valve. 4. The pump mechanism of claim 1, further comprising: a one-way pump inlet valve operable to pass the first fluid into the pump membrane. 5. The pump mechanism of claim 1, further comprising: a one-way pump inlet valve operable to pass the first fluid into the pump membrane,wherein the one-way pump inlet valve is formed from a peripheral portion of the depressor valve. 6. The pump mechanism of claim 1, wherein the liquid exit includes a liquid tube. 7. An apparatus comprising: a fluid container including an opening;an upper portion that sealingly couples to the opening of the fluid container, the upper portion including a liquid exit; anda pump mechanism coupled to the upper portion, the pump mechanism including: a pump membrane;a one-way pump outlet valve operable to pass a first fluid from the pump membrane to a pump air outlet;a closable flap including: a seal portion operable to seal the liquid exit, anda liquid deflector including a cupped portion extending outside the seal portion to redirect a direction of exit of liquid from the liquid exit;a spout rod including a first end coupled to the closable flap; anda depressor valve coupled to a second end of the spout rod, the depressor valve positioned inside the pump membrane, wherein actuating the depressor valve displaces the spout rod, opening the closable flap. 8. The apparatus of claim 7, wherein the closable flap is biased to close upon deactuation of a depressor valve. 9. The apparatus of claim 7, further comprising: a one-way pump inlet valve operable to pass the first fluid into the pump membrane,wherein the one-way pump inlet valve is formed from a peripheral portion of the depressor valve. 10. The apparatus of claim 7, wherein the upper portion includes a receiving depression operable to seat the pump membrane. 11. The apparatus of claim 7, wherein the fluid container includes vacuum sealed walls. 12. The apparatus of claim 7, wherein the upper portion further includes a drinking reservoir operable to collect the liquid redirected on exit from the fluid container. 13. A method for assembling a pump mechanism, including: positioning a closable flap at a liquid exit, the closable flap including a seal portion operable to seal the liquid exit, and a liquid deflector including a cupped portion extending outside the seal portion to redirect a direction of exit of liquid from the liquid exit;positioning a depressor valve in a receiving depression;coupling a first end of a spout rod to the closable flap and coupling a second end of the spout rod to the depressor valve;seating a pump membrane in the receiving depression; andpositioning a one-way pump outlet valve on a pump air outlet, the one-way pump outlet valve operable to pass a first fluid from the pump membrane into the fluid container. 14. The method for assembling a pump mechanism of claim 13, further including: coupling a liquid tube to the liquid exit.
